Have you heard of isagenix and what is your opinion of it?

Not favorable: These products are essentially snake oil. Many such compounds are marketed as having amazing results, regarding weight-loss, or wellness, or even treating complex diseases such as cancer. The "cleasing & healing" claims of such substances are totally unfounded, and their safety has not been ascertained in any large multi-center double-blind clinical trials.

Isagenix: i love it! I pair the supplementation with a healthy diet, exercise and lifestyle. I use it for patients who are also nutritionally deficient.
